Nothing. Downloading software does not affect currently existing software, but if "Open Office" automatically sets itself to open .doc (Microsoft Word) files, then the only way to open a file with Microsoft Word after that is either dragging and dropping the file onto the Microsoft Word icon or right-clicking on the file and selecting "open with > Microsoft Word"
Open Office will open Wordpad files without any difficulties. By default, Wordpad saves documents as 'rich text format' (.rtf) - you can specify different formats if you choose. OpenOffice will read rtf files without any problems.
